Study on Biogas Fermentation of corncob

The anaerobic digestion of corncob was assayed in batch reactors under ambient temperature(17-26℃).In the experiment,we study degradation productivity of corncob and biogas production,and analyse rapport between cellulose,hemicellulose and lignin.The result is that the time for fermentation is longer,that materials is not easily anaerobic digested directly(the productivity degradation of cellulose is larger than that of hemicellulose,and lignin is hardly digested).
